The point, by the way, is that scientists and popular-level atheist writers are notoriously inexperienced in philosophy, and repeatedly make the mistake of thinking that they can use empirical knowledge to prove that non-empirical knowledge does not exist. If we can just get people like Dawkins to stay within the realm of what he can demonstrate empirically, he would not make such big mistakes.

Knowledge of God exists in the realm of non-empirical knowledge……..at least with the qualification that God’s effects can be known empirically, but as I’m sure you well know, God’s effects are much disputed.

Knowledge of things that aren’t real also exist in the realm of non-empirical knowledge. That’s why skeptics aren’t buying the whole concept. But then again, that’s why it’s called faith. It’s believing when you aren’t sure.
